listy Posted June 20, 2012 Share Posted June 20, 2012 Could be the pads are too tight/need wearing in Quote Link to comment Share on other sites More sharing options...
RA28 Posted June 20, 2012 Share Posted June 20, 2012 have a look at the back plates. They bend quite easily and could be fouling on the disc. Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 20, 2012 Author Share Posted June 20, 2012 Back plates? You mean back of the pads ? Quote Link to comment Share on other sites More sharing options...
RA28 Posted June 20, 2012 Share Posted June 20, 2012 (edited) No, the ones that sit behind the discs.http://www.google.co.uk/search?q=supra+brake+back+plate&hl=en&client=safari&tbo=d&source=lnms&tbm=isch&sa=X&ei=dUbiT4GDIbGY1AXCs6zFAw&ved=0CE0Q_AUoAQ&biw=1024&bih=672#biv=i|53;d|Y5jvieyNKztKpM: Edited June 20, 2012 by RA28 (see edit history) Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 20, 2012 Author Share Posted June 20, 2012 Will check them in the morning, could be wen i was testing the brakes on rear by pumping the brake pedal that the fronts have tightened up and not retracted correctly ? Quote Link to comment Share on other sites More sharing options...
Nic Posted June 20, 2012 Share Posted June 20, 2012 (edited) Have you fitted the anti-squeak shims? Edited June 20, 2012 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 21, 2012 Author Share Posted June 21, 2012 Is that two long pins which sit ontop of the pads ? Quote Link to comment Share on other sites More sharing options...

mwilkinson Posted June 21, 2012 Share Posted June 21, 2012 No they go on the outside of the pads between the pad and the piston. Thin metal sheets, two for each pad. Edit - Beaten to it!! Grrrr...... Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 21, 2012 Author Share Posted June 21, 2012 I know what you mean now, no i havnt, like an idiot i have probably thrown them thinking they was something to do with the old brake pads Quote Link to comment Share on other sites More sharing options...

Brothy Posted June 21, 2012 Author Share Posted June 21, 2012 Found 3 lol, will they sort most of noise out till i order some more ? Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted June 21, 2012 Share Posted June 21, 2012 Best just fitting all new ones tbh mate - mine were horrendous until I changed them and installed new spring clips (shound be 2 on each side to push the pads apart and keep them off the wheel). Quite an easy bit to forget! Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 21, 2012 Author Share Posted June 21, 2012 I suppose i would have to wait for them to be orded from toyota wouldnt i Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted June 21, 2012 Share Posted June 21, 2012 You may be lucky, they could have some in stock. Or maybe try Paul at Whifbitz? Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 21, 2012 Share Posted June 21, 2012 While your waiting i'd be checking its not the calipers seizing up. Do you have the smaller 2 piston fronts or larger 4 piston (uk spec) ? Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 21, 2012 Author Share Posted June 21, 2012 2 piston mate Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 21, 2012 Share Posted June 21, 2012 Check the caliper is moving freely on the sliding pins and also check the pistons move freely. I've left the anti squeal shims out on my 4 piston (uk spec) and they don't make any noise but they do have a smear of copper slip on them Quote Link to comment Share on other sites More sharing options...
stevie_b Posted June 21, 2012 Share Posted June 21, 2012 No they go on the outside of the pads between the pad and the piston. Thin metal sheets, two for each pad. Are you sure it's two shims per pad, or should that be two per calliper (i.e. 1 per pad)? Quote Link to comment Share on other sites More sharing options...
Nic Posted June 21, 2012 Share Posted June 21, 2012 Are you sure it's two shims per pad, or should that be two per calliper (i.e. 1 per pad)? 2 shims per brake pad on the 2pot front brakes. 1 shim per brake pad on the 4pot front brakes.

garethr Posted June 21, 2012 Share Posted June 21, 2012 (edited) Two for each pad. SHIM KIT, ANTI SQUEAL, FRONT - 04945‑14010 Edited June 21, 2012 by garethr (see edit history) Quote Link to comment Share on other sites More sharing options...
Brothy Posted June 21, 2012 Author Share Posted June 21, 2012 Just checked front left side and noticed the back plate is touching the disc, gone chop away the part that contacts the disc when the rain desides to slow down then will check the drivers side, is it safe to put a bit if copper grease on the pads ?

stevie_b Posted June 21, 2012 Share Posted June 21, 2012 Brothy, are you sure it's been fitted properly? That doesn't sound right at all. Do you mean the anti-squeal shim is touching the brake disc? Quote Link to comment Share on other sites More sharing options...
